I only know the Dawson's Heights and Arnold Circus ones. I'll have been on the Pimlico one quite recently but it's left no memory whatsoever, which I suppose is comment enough. I used to live opposite Dawson's Heights in Overhill Road - my daughter was conceived there - but it was far less inviting than a rocky outcrop that dominated the hill top would have been. Even those Google map cars seem to have been frightened away. I like Arnold Circus, it has a feeling of solidity and calm about it and - rare enough for councillery - its roads are quiet and actually go somewhere. It doesn't have that typical dead end feel to it.
My own council estate suffers a little from that dead end feel though there is a fair amount of cross-estate movement from cyclists and pedestrians.
Oh, and what's wrong with calling it a council estate? I can't think of another useful title for where I live.
